I bought a heavy bag off NYspeed last year or the year before and put it up a few months back. I installed it in a pretty straight forward manner as can be seen below, however, because i tied it right into the floor board and because the house is 50+ years old it’s causing too much vibration and shaking the whole main floor. My wife is giving me shit for it.
So, i need to find a way to make it not shake the whole place… I was told i should use canvas strapping instead of the chains, which i can do, but what else can i do to significantly reduce the house-shakery?
unfortunately since the you are using a heavy bag, it won’t matter what material is used in place of the chains. It will still be an obscene amount of force being directed to the hook in the floor board.
I had a 40lb bag mounted at my parents many years ago in the basement. It was mounted to the steel i-beam that ran through the center of the house. There were 2 basement poles on either side of the bag (only 8ft apart) running from the i-beam to the basement floor. Even at only 40lbs, that thing would still shake the shit out of the house, and the house was only about 12 years old.
A friend of mine had a 1 year old house and he mounted his heavy bag in the same way (to a steel i-beam) and the same thing happened.
With mounting it to wood, you pretty much are out of luck completely.
The only way to really eliminate it is with a punching bag stand, which you said you can’t do. Even then, the concussive sound of hitting the bag will still put some noise and slight vibration through the house.

Maybe something like this would be an option, if you feel ok with drilling and putting lags into the basement wall (assuming the wall is safe to do that to)
Attach accelerometers to the system at multiple locations, record the data while using the bag to see what frequencies are being excited, order a custom tuned resilient mount to attentuate those frequencies.
Or if you want to do it the hard way , maybe try a heavy spring to hang it and some isolation with rubber pads.
Give it a shot but I think that those will be too high of a spring rate and won’t dampen the shock. Try a truck snowplow shop. They have some medium duty springs that should work. Some of them already have rings on the ends of the spring. One other thing that may help would be to hard mount the end that attaches to the wall/ceiling. Much of the shock load that is jarring the house is when the bag ring jumps up then slams back back down on the mount ring.
I don’t see you having any real success. I have a 100lb heavy bag i’ve had attached to to wooden beams in the basement, and it did the exact same thing. I tried mounting in different areas, but it always vibrated entire house. I tried running it on ropes instead of chains and all kinds of shit, none of it really made any noticeable improvements. If you can run a stand by drilling into the wall then you might have some success, but you said a stand is no go.
